MAKING A RETURN ON INVESTMENT IN PASSIVE ARCHITECTURE TERRACED HOUSES DEVELOPMENT Wan Rahmah Mohd Zaki Universiti Teknologi Malaysia(UiTM) Malaysia E-mail: [email protected] Abdul Hadi Nawawi Universiti Teknologi MalaysiaQJiTM) Malaysia E-mail: [email protected] Sabarinah Sh Ahmad Universiti Teknologi MalaysiaQJiTM) Malaysia E-mail: [email protected] ABSTRACT The main feature of a conventional terraced housing development is rows of rectangular shaped houses with the narrow facade as the frontage. Consequently, this limits natural cross ventilation and daylight penetration into the middle of the houses; and cause for unnecessary energy consumption on mechanical cooling and artijicial lighting to make the living spaces comfortable for occupants. Such inconsideration is mainly attributed to the optimum configuration of houses which offers the most economic return desired by the developer. Passive Architecture (PA) design strategies can make terraced houses more conducive for occupants as well as gives reasonable returns to the developer. The idea is demonstrated on a hypothetical double storeys terraced scheme in a 2.5 acre site whereby it is transformed intofour types of PA terraced houses development. The Return on Invesfment of the PA terraced houses is ascertained for two situations, ie., (i) fwed sales price for all types of house; and (ii) added premium to PA terraced houses due to the positive unintended effects such as low density housing, etc. If critical criteria for demand and supply in housing remain constant, it is found that PA terraced housing development offers competitive returns to the developer relative to the returns for conventional terraced housing scheme.

It’s not only a place to prepare and eat food, but also a place to relax, a place to entertain, and a place to enjoy. It should be inviting, bright, functional, and easy to control. The right kitchen lighting will help you stay clean, organized, and safe, while letting you create the perfect atmosphere for an early morning baking frenzy, board games with the kids on a rainy afternoon, or spending a couple’s night in. Most of all, light layering (having multiple light sources for different purposes) is the most important, all-encompassing rule in kitchen lighting design. A single light source never does any space justice. You need different sources of light for different purposes. Ambient lighting, task lighting, accent lighting, safety lighting, and mood lighting are all essential parts of great kitchen design. This book will first and foremost address task lighting in the kitchen. Under cabinet lights are the most popular, attractive, and handy kind of task lighting for the kitchen. Lighting designers agree that the path to any beautiful, functional kitchen starts with excellent task lights. Kitchen task lights have one simple purpose – to help you out. -

Lighting Your House
LIGHTING YOUR HOUSE Lighting accounts for approximately 5 to 10 percent of your household energy bill. This amount may not seem like a lot, but it can add up quickly. Energy efficient lighting is easy and results in immediate energy savings to lower your bill. Light-emitting diodes (LEDs) Save the most money on energy costs, upwards of 75 percent. Additionally, they can last 20-30 times longer than incandescent bulbs. Their versatility allows them to be used in a variety of applications, including as outdoor and holiday lighting. POTENTIAL SAVINGS Check out the potential savings you can see by replacing just five of your more frequently used bulbs with energy efficient alternatives. TYPE OF BULB Incandescent (60W) CFL (13W) LED (10W) $2.50 $10.00 $15.00 Approximate Cost (5 bulbs at $0.50 each) (5 bulbs at $2.00 each) (5 bulbs at $3.00 each) Life Span When Used 3 Hours/Day, 7 Days/Week ~10 months ~9 Years, 1 month ~22 years, 9 months Number of Bulbs Needed 125 13 5 in LED Life Span Yearly Electricity Cost (11.3¢/kWh) $37.12 $8.04 $6.19 Lifetime Savings with LED $756 $62 - - - 1 LIGHTING YOUR HOUSE RECYCLE BULBS Check you local waste and recycling department.

Two critical features to keep in mind are watts and lumens. Watts (W): The amount of energy a bulb uses to produce light, or how much energy the bulb consumes.
